Título del libro: Proceedings - 2010 Ieee Electronics, Robotics And Automotive Mechanics Conference, Cerma 2010 Título del capítulo: Dynamic Visual Servoing of Robot Manipulators Based on Passivity
In this paper the servo problem in a 3-D robot manipulator based only on
the visual measurements by following the dynamic visual servoing
approach with a fixed camera configuration is considered. To model the
whole visual servoing system, we consider the robot in an image space,
reconstructed from the perspective projection of the robot space in the
image plane. The manipulator dynamics is lifted up to the image space
and modeled with the lagrangian formalism by formulating the kinematic
and potential energy in the image space. The resulting motion equation
has the same structure as that obtained in the joint space using the
lagrangian modeling [1], and therefore inheriting the passivity
property. Control schemes based on the passivity of the motion equation
are then designed for visual servoing. Simulation and experiment results
are included.
